Planck Mass

What is a planck mass?

The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.

Origin of the planck mass

Introduced by Max Planck in 1899 as part of a system of natural units.

Where it is used

Theoretical physics and quantum-gravity research.

When and where it was developed

Defined by Planck in 1899 from fundamental constants.

Metric / SI

Decigram

What is a decigram?

A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.

Origin of the decigram

From the SI prefix 'deci-' (from Latin 'decimus', tenth).

Where it is used

Occasional laboratory and pharmacy use.

When and where it was developed

Part of the original metric system of 1795.

Planck Mass to Decigram conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between planck mass and decigrams:

1 mP = 0.000217671 dg
1 dg = 4594.0892447777 mP

To convert planck mass to decigrams, multiply the value in planck mass by 0.000217671. To reverse, multiply decigrams by 4594.0892447777.

How to use this converter

Type a value into the calculator. The result in decigrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Decigram to Planck Mass converter for the reverse direction.

Step-by-step: convert planck mass to decigrams

  1. Write down the value in planck mass (mP).
  2. Multiply that value by the factor 0.000217671.
  3. The product is the equivalent value in decigrams (dg).
  4. To reverse, multiply the decigram value by 4594.0892447777.

Worked examples

Example 1 — Convert 1 mP to dg:
1 × 0.000217671 = 0.000217671 dg

Example 2 — Convert 100 mP to dg:
100 × 0.000217671 = 0.0217671 dg

Real-world example — Sub-visible-light wavelength

500 planck mass (the green-yellow visible band) equals 0.5 decigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 mP × 0.000217671 = 0.1088355 dg

Real-world example — Spanning sub-micron to micron scale

Crossing from planck mass to decigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 planck mass translates to a much more compact value in decigrams that fits the scale of biological cells and process nodes.

1000 mP × 0.000217671 = 0.217671 dg
